School Research Seminar: High performance CdTe based photovoltaics: Progress and Challenges

Thursday 29th June 2023, 12.00 – 1.00 pm, DAV 1100, Sir David Davies Building

Dr Eric Colegrove

National Renewable Energy Laboratory (NREL) Denver, United States  

Eric Colegrove is a staff scientist at NREL with more than 10 years of experience in cadmium telluride (CdTe)-based solar photovoltaics (PV) research and development. His graduate work focused on arsenic doping of single crystal CdTe thin-films deposited by molecular beam epitaxy (MBE). His postdoc appointment at NREL continued this work, expanding from single crystal model systems to large grain polycrystalline material and additional group V dopants including phosphorus and antimony. Recently, as a staff scientist, his research focus has shifted to challenges associated with implementing group V doping in polycrystalline thin-film devices while supporting various other inter-related research efforts to improve the performance and stability of CdTe based PV materials.
